Is it possible to open self-signed java applet with java version 7 update 51 without decreasing security level

Question

An application run as java applet suddenly stopps working with default java security settings.

The reason is that this applet uses a self-signed certificate.

Is it possible to get it starting again without lowering the security level configured within the Java control panel? Is there any workaround?

You might also consider packaging your application up using something like Launch4j, JarSplice, or JWrapper. — Kevin Workman, Jan 15 '14 at 18:45

I strongly suggest using a certificate signed by a good Certificate Authority (CA). If you can modify the client machine, it is possible to add your own CA, but the practice is frowned upon for being somewhat dodgy.

Java uses its own list of CAs also. [How to import .cer file in to .truststore](http://stackoverflow.com/questions/373295/digital-certificate-how-to-import-cer-file-in-to-truststore-file-using). Search for "code-signing certificate". – Marcus Adams Jan 15 '14 at 15:52
